Abstract
Abstract An apparatus for cutting hair includes a tube defining an air flow path with a cutting device located in a cutting zone in the flow path. The cutting device includes a rotor and a stator which co-operate in a continuous scissors like manner with the rotor being moved by a small air driven turbine. The apparatus is adapted for connection to a vacuum cleaner to provide an air flow in the air flow path and to drive the turbine.

A haircutting apparatus comprising a means defining a flow path having an inlet and an outlet, said outlet being adapted for connection to a section device for generating an air stream through said flow path; a cutting zone in said flow path; and a haircutting device located in said cutting zone comprising a turbine rotor arranged in said flow path to be rotated by the air stream and a rotary cutter having a stator blade and a rotor blade, said rotor blade coupled to and rotably driven by said turbine blade, said stator blade having an annular cutting member with an inner circular cutting edge; said rotor blade having a disc cutting member abutting said stator blade and having an outer cutting edge; said disc cutter member having a central axis, said annular cutter member having an axis, said axis of said disc cutter member being offset from the axis of said annular cutter member; and the axis of said disc cutting member being movable in a circular path about said axis of said annular cutter member such that said inner and outer cutting edges cooperate in a continuous scissor-like manner so as to cut hair which has been drawn into the inlet of said flow path by the section device.
